Repeatedly, Numbers does not successfully open xls files for me. Results look like: "?xml version="1.0" encoding="UTF-8"?>" ...
I'm having trouble opening an xls file in Numbers. Numbers opens it but the result is a long string of xml encoding. I've tried changing delimiters, etc., without success. All documentation says opening xls should be automatic. But something is amiss. Please advise. Thank you.
